What can be inferred about a petrified log? the wood needed long ages before it could petrify the tree laid on the surface for l
RideAnS [48]

Answer:

the petrified log looks like the original tree.

Explanation:

A tree to be petrified first needs to be buried. An element laying on the surface can not be petrified because it is exposed to many different factors (such as<em> organisms, microorganisms, climatic conditions</em>, etc.), that affect the petrification process. So, in the case of a fallen tree, first, it needs to be covered by many sedimentary layers. Once it is underground, it also needs the presence of underground water and minerals. Water replaces the original organic material with minerals (silica, calcite, and pyrite). This replacement process results in the conversion of the woody material into a fossil of the original material. Very often, the tree details are so preserved that the fossil looks exactly like the original trunk.

Depending on the preservation degree, a fossil can be useful for different studies about the past.

Bacteria undergo mitosis and meiosis in order to reproduce and increase genetic recombination.
Salsk061 [2.6K]

Answer:

The correct answer is (b)-False

Explanation:

Bacteria do not undergo meiosis or mitosis to reproduce and increase its genetic recombination. To increase their genetic recombination bacteria take the help of horizontal gene transfer through which it gets the genetic material of another bacteria. This new gene helps bacteria to survive in the challenging environment.

Bacteria divide through binary fission in which one cell of bacteria divides into two equal daughter cell each having its genetic material because genetic material of parent cell segregate equally into both the cell.  

Therefore bacteria do not undergo meiosis or mitosis.
